Published: April 2022

Electrodes for electrochemical reduction of graphene oxide (GO) are coated with thin films using drop-casting and evaporation-assisted self-assembly. The influence of loading, the size of the flakes of GO, and the macroscopic coffee-ring effect occurring during drying are investigated. The effective transfer of protons and electrons in the electrochemical reduction of GO is decisive.

Background: Atrazine (ATZ), a pesticide that poses serious health problems, is observed in the environment, thereby prompting its periodic monitoring and control using functional biosensors. However, established methods for ATZ detection have limited applicability. Two-dimensional (2D) metal azolate frameworks (MAF) have a higher surface area per unit volume and provide easier access to active sites.

Article Synopsis
  • Glucose sensing is essential for managing diabetes, and this study explores NbCT-selenium nanoparticles for effective nonenzymatic glucose detection.
  • The composite material was characterized using techniques like scanning and transmission electron microscopy, and it was tested on a gold disc electrode in an alkaline solution.
  • The sensor operates at a low overpotential of 0.16 V, demonstrating a detection range of 2 to 30 mM, with a notable sensitivity of 4.15 µA mM cm and a detection limit of 1.1 mM.

Bloodstream bacterial infections, a major health concern due to rising sepsis rates, require prompt, cost-effective diagnostics. Conventional methods, like CO-based transduction, face challenges such as volatile metabolites, delayed gas-phase signaling, and the need for additional instruments, whereas electrochemical sensors provide rapid, sensitive, and efficient real-time detection. In this study, we developed a bioreceptor-free Prussian blue (PB) sensor platform for real-time bacterial growth monitoring in blood culture.

As an accelerated electron transfer device, the influence of microbial electrochemical snorkel (MES) on soil greenhouse gas production remains unclear. Electron transport is the key to methane production and denitrification. We found that the NO amount of the MES treatment was comparable to the control however the cumulative CO and CH emissions were reduced by 50% and 41%, respectively.

Anion exchange membrane fuel cells (AEMFCs) are among the most promising sustainable electrochemical technologies to help solve energy challenges. Compared to proton exchange membrane fuel cells (PEMFCs), AEMFCs offer a broader choice of catalyst materials and a less corrosive operating environment for the bipolar plates and the membrane. This can lead to potentially lower costs and longer operational life than PEMFCs.
